Internal Mold Releases

When situations arise that require new thinking, Chem-Trend thrives. Internal mold releases (IMR) can also be used for composite molding. IMRs are typically comprised of an additive blend in solid or liquid form which is pre-mixed into the resin prior to molding. During the cure process, the IMR becomes immiscible in the resin, phase separates and blooms to the surface, creating an outer lubricating layer at the interface of the curing part and mold substrate. We have developed special internal release agents for the composite molding industry that are utilized for two major purposes:

• Enhance the function of external release agents. Keeping the mold surface clean and free from buildup for an extended period of time. This saves time and labor, and it preserves the integrity of your products.
• Provide internal lubrication to the resin. For certain situations, this provides a game-changing element to the manufacturing process as well as the future use of the resulting product.
